alright, i've got a wierd goal to go cliff jumping in every country I travel to, and so far I'm on track. I'll be travelling around SE asia for about 4 months this summer, and I was wondering if anyone knows of any good spots in cambodia, vietnam, laos, and thailand. It's a little bit of a random enquiry, but hey, I figured these forums would be the most likely spot to get some info. so, anyone know of any good cliffs to jump off of?
Kuang Si falls near Luang Prabang in Laos have a spot where you can scramble up to a ledge next to the waterfall and jump into the water.

haha, i guess i should have been a bit more specific, but thanks for all the replies. Just looking for known spots anywhere from about 10-50 feet, definitely somewhere that's a reasonably well known spot so I can be sure that the water is deep enough (I do have travel insurance, but i'd rather not have to use it for hospital expenses after breaking my neck). once again, thanks for the tips everyone!

Oh....I have jumped about 30 feet off a cliff at a waterfall north of Pai, thats was a blast, in August of 2003.
Laos, I jumped off a cliff at a waterfall north of Luang Prabang, and also near Vang Veing. Also east of Pakse at at Tat Fan? These are only about 30 feet up, into rushing water though, not calm pools...
In Vietnam, the best was the Ba Ho watefalls north of Nha Trang on road to Doc Let, huge boulders to climb up a great valley and river, with 3 places to jump, the highest was about 40 feet, and I screamed all the way down....
It does depend on water levels too obviously. I also always watch the locals jumping first, and would not jump unless someone from the area jumped ahead of me....
PS- I am scared of heights, so this activity for me is really a personal challenge.
